PURPOSE: A desk assembly is provided to control a desk table to move back and forth to be fitted with a user's physical conditions. CONSTITUTION: The desk assembly includes a fixing unit to safely position table(30) in a level frame(21) to be sliding-movable and to fix the table at a predetermined position of the level frame. The fixing unit includes a moving block(50) to form a receiving groove fixed on the bottom of the table to receive the level frame and a penetrating hole with the receiving groove to pass through in a horizontal direction; a fixing block(60) with a guide rib received in the receiving groove and fixed to the level frame to form a fixing groove at regular spaces, the guide rib being projected into the penetrating hole; a fixing knob(70) to form a separating groove in which the guide rib is sliding-movably connected and to form a fixing projection which is sliding-movably connected with the penetrating hole and connected with the fixing groove; and a spring to elastically fix the fixing knob(70) to the moving block(50) such that the fixing projection is positioned in the fixing groove and the separation groove is positioned in the guide rib. Thereby, the desk assembly enables a user to take a seat to control the table to move back and forth to be fitted with the user's physical conditions so that a user takes the comfortable and stable pose.
